2 Claims.

This invention relates to a shipping container for a building material and more specically to a container for storing and shipping an extruded plastic material.

The material under consideration is more fully described in copendng application, Serial No. '367,042, led November 25, 1940.

It is an object of thepresent invention to provide a packaging method and arrangement which will permit the storing and shipping of the extruded material without danger of Skinning-over or oxidation and without danger of crushing. A further object of the invention is the provision of a space within the container for a sealing liquid which is to be used with the building material.

Other objects and features of the invention, having to do with details of the packaging process and the construction of the elements of the package, will be brought out in the following description and claims.

In the drawing:

Fig. 1 is a vertical axial section showing the arrangement of the parts.

Fig. 2 is a section on line 2-2 of Fig. 1.

Fig. 3 is a perspective View of one of the selfspacing discs.

Fig. 4 is a sectional View of a modified type of disc.

A cylindrical container l0, having a closed bottom ll, is provided with a sealing top I2 in which is located a valve attachment I3. Within the container are Seli-spacing discs l5 which are formed from at sheets of brous or other suitable material. The edges of the disc are preferably notched out at I6 and turned up -to form the spacing elements I1 arranged on a diameter substantially equal to the inner diameter of the container. Some of the discs l5 are centrally apertured at IB and arranged adjacently to provide a cylindrical opening for a container 2B. This container holds a bonding material to be used with the plastic material when the stone which is to be jointed is dusty or moist. A brush 2l is mounted directly on the cover of the container 20. The plastic material 25 is arranged in coils as shown in Fig-2. On the solid discs at the lower end of the can, a small plug 26, which is of cork or other suitable material, may be used to start the coil and to serve as a spacer for the central portion of the disc. In Fig. 4 a modified apertured disc is shown having axially extending portions 2.1 to surround the container 20 and serve as a spacing element.

In packaging the material, the extruded material is first arranged in coils on the discs which are placed in spaced relation in the container. By using the valve connection I3, air may be substantially exhausted lfrom the container after the cover is applied and the container may be lled with an inert gas such as carbon dioxide under a pressure slightly above atmospheric.

We claim:

1. A packaging arrangement for plastic extruded building material comprising a cylindri- .cal container, a series of discs arranged to be spaced axially in said container, and coils of the extruded plastic material arranged on each of said discs, certain consecutive discs being apertured, and a container for sealing liquid positioned in the cylindrical opening formed bythe apertured discs.

2. A packaging arrangement comprising a cylindrical container, a series of self-spacing discs in said container each formed from a flat circular blank and having the outer edges of said blank turned axially thereof to form spacing elements for said discs, certain of said discs being centrally apertured with an axially extending flange portion, also serving as a spacing element and arranged consecutively to form a cylindrical opening, and a container for sealing liquid positioned in said opening.
